    No spark out of distributor - Mercruiser 140 I/O

    3.0 s are always loud. Id swear on the trailer my 3.0 in my previous boat was louder than the 5.0 in my current boat id hang onto your points as both on here and the muscle car forums you tend to see a fair amount of pertronix failures. If you cleaned points and set dwell they would probably...

    Wideband O2 sensor install

    When you are cruising along 3200-4000 rpm that is part throttle, not highway cruise which can go leaner than 14.7, but it it not WOT acceleration. if your cruise is basically ok you just need a leaner rod on the rich/ power end and leaner secondary jets. probably want to get the afr tweaked in...

    Yeah those are typical rpm ranges. The older ones seemed to have lower wot than later ones With GT40 heads etc. im not a ford expert but general rule of thumb for stockish V8 s keep it under 5 k and it will live…

    Wideband O2 sensor install

    Do you have this edelbrock tuning manual ? https://www.edelbrock.com/media/wysiwyg/documents/carb-owners-manual.pdf the secondary uses the same jets as primary, just different orrafice size. the reason you have two step rod in any application is so you can have a different fuel mixture at part...

    Water in Oil (Again) Head Scratcher

    It would seem you have eliminated all engine issues so must have come in through the carb. Not sure if your sunpad has a seam over carb or not. Do you have a flame arrestor cover on it ? These are intended to keep water out of the carb and distributor.they get on the way so people toss them...

    speedometer pick up tube

    The exhaust bellows are already full of water. The exhaust is open to water on the prop end… also the cooling water that comes out of the engine after getting warm is discharged overboard by the exhaust

    Over-Temp alarm installation

    All chicks and disco balls aside looking at the specs for that kit the temp switch trips at 200 F. Not sure if that is too high for a 3.7? I was under the understanding that the 3.7 was very intolerant to even minor overheats before it spits a head gasket. Not sure if others here can confirm...

    Over-Temp alarm installation

    you dont need to buy a kit . You can make your own just take power off the ignition on circuit the two switches can be OEM merc ones to make the ground connection to the block as in attached diagram. Would just make sure the temp switch is correct for the 3.7 that is overly sensitive to over...

    Popped through the intake.

    This is odd - is the top of the coil cracked? Only things I could think of is its coming out of the coil top, the wiring harness is too close and its jumping from HT wire, or you dont have a great cap to rotor connection and the spark has no where to go- only time I saw this was disconnected by...

    Ford 302 5.0 H.0. Carburetor omc Cobra stern drive outboard best prop

    yes if you want to improve planning performance yes drop in pitch. How does your current WOT rpm compare to what the engine is rated for? Is the engine in a good state of tune ?

    First time pulling an engine questions

    yes it takes about an hour if you are reasonably familiar. yes you can weld a patch over the rust hole. just completely check it out as you may have small pitting and not worth messing with it.
